closely. first, let me give you an idea of how this has happened. here's how the system, according to the s.e.c., should have worked. goldman sachs was creating pools of investments, so you took a mortgage with the bank. the bank sold that mortgage to another entity and at some point goldman sachs was responsible for taking all of those mortgages, pooling them together, taking a piece of the action and sell it off to other investors. now, this is a skill, because some of the mortgages in that pool would have been good. some of them would have been less good. they were all subprime. they were all those loans given to people, perhaps not with the greatest of interest. but the bottom line is, they were sold as investment pools, and they could have gone up or could have gone down. that is what should have happened. here's wharp the securities and exchange commission said did happen. here's what their allegations are. goldman sachs did the same thing. they pooled these mortgages and sold them to people, but they had an outside adviser, also another client, determine what went into this pool, what sort of houses went into this pool,
